After years of not doing any iv shit I shot some methylphenidate. When I did it the first time, I used around 20 mg. I solved it in water, and filtered it through a cigarette filter. The solution was still only slightly milky, not completely clear. I knew that insoluble particels were in there. But as I was kind of suicidal anyway I thought fuck it, I want that kick now whatsoever...
There was a slight kick and strange feeling to the scalp (needles and pins). It's a mild form of speed (with which I didn't have much experiences). After I did this one or two times (!), I got a slightly numb feeling in the tip of my left foot. I was basing very bad, poisonous coke at the time, too. But I am quite sure that the pill injecting accounts for the numb feeling (capillary veins clog.., lack of oxygen in tissues, nerve tissue probably damaged, etc.).
Now I started to filter the solution more thoroughly with a cigarette filter tightly wrapped in filtering paper (the type for quantitative analysis, from chemical laboratory equipment store). If you do that, it's nice to see to it, that the filtering paper doesn't hold additives. The solution appeared after that like water. In the next week I shot around almost another 100 mg ritalin in some doses (biggest was 30 mg in 2 ml of water, I think). I read that by solving methylphenidate-HCL in water, a small amount of HCL-Acid will be spawned.
And when I shot 30 mg, I definately had a very strange, bad feeling in the vein upwards from the injecting point in the direction of my heart, like a burning sting along the vessel. This persisted for some time. The kick was a quite intense speed rush, where I had to get moving, do something. (I went in front of the hospital by foot, in case some shit happened, and waited there some time
. I also shot up subutex in that time (which seems to be easier to filter to waterlike-clearness)
After the whole story I still have a slight feeling of numbness in the tip of my foot, and then also in the tip of my right index finger.
So do watch out if you think you want to do this. A couple of badly filtered pills might give long lasting damges, or whatever else.. It is very risky aside from the already known dangers of iv usage.
In a way I can hardly believe that I acted so stupidly. I even knew the risk. Welcome to addiction, ignorance and stupidity.
